Patent JP-H04130856-A (JP)
Title: Line terminal equipment
Inventor: IGUCHI JUNJI
IPC: H04M11/10
Filed: 1990-09-21
Abstract: PURPOSE:To prevent sound from becoming difficult to be heard owing to the level difference of both signals at the time of monitoring a line or at the time of recording and reproduction by detecting an opposite signal and a transmission signal from a mainbody device and controlling the level of the opposite signal and that of the transmission signal to be the same. CONSTITUTION:A circuit signal detection means 1 detects signals on lines L1 and L2 and they are converted into digital data in an A/D converter 3a. At the same time, the transmission signal detected by a mainbody transmission signal detection means 2 is similarly converted into digital data in an A/D converter 3b. Both signals are transmitted to a subtraction circuit 4 and a signal which is D/A concerted by a D/A converter 5 is converted into an analog signal by a low pass filter 6. Then, a level detection circuit 8 judges it. On the other hand, the transmission signal which the mainbody detection signal, detection means 2 detects passes through an amplification factor variable amplifier 7 and a level detection circuit 9 judges the level. A comparison circuit 10 controls the amplification factor of the amplification factor variable amplifier 7 to become the same as the level of the opposite signal after it passes through the low pass filter 6.

IPC: F16L55/18
Filed: 1989-09-25
Abstract: PURPOSE:To make it possible to safely practice all works from the outside of a pipe with no need of stopping flow of sewage by incising a FW pipe having a bore diameter nearly equal to the outer diameter of an obsolete sewer in axial direction, putting the same over the outer periphery thereof, in close contact thereto. CONSTITUTION:In the case of an underground buried pipe, first the earth is dug up till side face part of a sewer 1 so that it may be exposed. Next, the sewer 1 is mended in such a manner that a pipe 3 incised in axial direction to be a FW pipe 3 whose bore diameter (r) is nearly equal to the outer diameter R of the sewer 1, is opened along an incising line 4, put the same over the outer peripheral surface 2 of the sewer 1, in close contact thereto. And in the case of the buried pipe, the construction is finished when the ground is returned to its original state to bury the pipe. As the result, the obsolete sewer 1 is covered with the FW pipe 3 on the outer periphery thereof, moreover brought in close contact thereto with soil pressure, and even if the inside of obsolete sewer 1 is eroded to generate a broken hole, leak never occurs. Besides, being superior in chemical resistance, the FW pipe 3 is never eroded if it touches any erosive gas generated from sewage.

Title: Two-cycle internal combustion engine
Inventor: NIHEI HIROAKI
IPC: F02B17/00
Filed: 1987-10-06
Abstract: PURPOSE:To obtain a good layer by opening an air supply control valve when an engine load is lower than a predetermined level during low load operation of engine. CONSTITUTION:An air supply control valve 16 arranged in a branch path 13b is closed when an engine is operated with relatively high load during low load operation, and fuel is ejected only through a first fuel injection valve 10a regardless of load during low load operation of engine. Consequently, fresh air containing fuel is fed only through a first air supply port 9a during load operation of engine. The air supply control valve 16 is opened for a low engine load even during low engine load operation. Since fresh air is fed from both air supply ports 9a, 9b, flow speed is decreased to weaken enhancing function of a swirl. Since turbulence provided to mixture gas is weakened, quantity of mixture gas to be dispersed downward is reduced thus remaining sufficient quantity of mixture gas around an ignition plug 8.

Title: Solid-state image pick-up device
Inventor: TABEI MASATOSHI
IPC: G03B7/00
Filed: 1987-10-06
Abstract: PURPOSE:To cause a processing to be a high speed and to improve performance by transferring the signal potential of a partial area in the reverse direction of an image output at a photometry time and reading it from a second horizontal CCD. CONSTITUTION:A second horizontal CCD5, which has a size to correspond to the partial area to be limited in the horizontal direction of a photo-detecting element group, is arranged in a side to face to a first horizontal CCD3 to execute the normal image output. A signal reading at the photometry time drives the signal of the partial area to be limited in the horizontal direction at a double speed in a vertical direction. Then, the signal is read with using the second horizontal CCD5 whose step number is smaller than the horizontal CCD3 to be used for the normal image output. Thus, practical priority photometry goes to be possible and the reading speed of a video signal can be extremely improved. In addition, the time needed for the processing for determination of various photometric dimensions, etc., in the image pick-up equipment of an electronic camera, etc., can be markedly shortened.

CONSTITUTION:Based on a signal TWI from a supplied water temperature detector 4, a signal TWR of a temperature setter 5 and a signal Fw1 of a water quantity detector, a temperature controller 3 determines a prescribed burning amount Qg, controls a supplied heat quantity controller 7, and opens a safety valve 9 provided in parallel with a faucet 8 when the result of an operation of the burning amount Qg turns to be below the minimum burning amount Qmin enabling the control of safe burning, so as to vary the quantity of water flowing through a heat exchanger and thereby to control the temperature of hot water fed from the faucet. This constitution works to enable the control of a temperature below the minimum burning amount of a burner and the attainment in a wide range of the quantity of water and the desired temperature set by a user. At the same time, an extraordinary high temperature of fed hot water caused when the quantity of supplied water is decreased is eliminated, whereby the safety is increased and the lifetime of the main body of a hot water feeder is prolonged.
